SUMMARY

The required altitude for geosynchronous satellites above the Earth is 3.59 x 107 meters. This value is derived using the equation (R3)/T2 = (G*M)/(4π2), where R is the radius from the center of the Earth, T is the orbital period, G is the gravitational constant, and M is the mass of the Earth. By rearranging this equation and substituting the known values, one can calculate the necessary altitude for a satellite to maintain a geosynchronous orbit.

PREREQUISITES
  • Understanding of Kepler's laws of planetary motion
  • Familiarity with gravitational equations and constants
  • Basic knowledge of orbital mechanics
  • Ability to manipulate algebraic equations
NEXT STEPS
  • Research the gravitational constant (G) and its significance in orbital calculations
  • Learn about the differences between geostationary and geosynchronous orbits
  • Explore the implications of altitude on satellite communication and positioning
  • Study the derivation of Kepler's laws and their applications in modern astronomy
USEFUL FOR

Aerospace engineers, astrophysicists, students studying orbital mechanics, and anyone involved in satellite technology and deployment.

Homework Statement



Using a development similar to Kepler's law of periods for planets orbiting the Sun, find the required altitude of geosynchronous satellites above the earth.

Homework Equations



(R^3)/T^2=(G*M)/(4pi^2)

The Attempt at a Solution



I'm honestly not even sure where to start. The correct answer is supposed to be 3.59*10^7m above the surface.

Well you know the period and you want to find the radius. Just rearrange the equation and plug the numbers in.
